An application has been filed in Germany June 6, 1929.

The present invention relates to an apparatus for wet-treatment,especially for washing textile goods in the form of fabrics.

The main obj ect of this invention is to provide an apparatus with aporous band immersed in the washing liquid, taking the teX- tile goodsalong in a plaited form and dipping it more or less into the liquid,according to the kind of the fabric, whereby the latter is sprinkledfrom above with the same liquid at the same time.

A further object of my invention is to provide means for changing thedepth of immersion and the sprinkling surface of the fabric.

My invention will be best understood when described in connection withthe accompanying drawings in which Figs. 1 and 1a show a longitudinalsection, Fig. 2 a partial cross section, Figs. 3 and d show differentways of conducting the fabric.

1 designates a tub for the washing liquid, 2 shows uprights placedpartly inside, partly outside the tub 1. To the uprights 2 trav erses 3and 5 are connected, carrying the chains 6 of the band 7 and also thebearing S for the reel-shafts 9. On the traverses 3 bearings 10 aremounted, taking up shafts 11, 11, upon which chain wheels 12 driving thechain 6 are fixed. The shaft 11 carries a chain wheel 13, actuated in awell known manner by the driving parts, viz. chain 1e, chain-wheel 15,speed reduction parts 16, i7 and 18 and which serves for the drive ofthe chain 6 and the band 7.

Upon the shafts 8 reels 2O are placed, showing dented rims and engagingwith pinions 22 sitting fast on a shaft 24, lodged in bearings 23together with a driving pulley 25, the latter thus being able to causethe reels to rotate.

ln order to be able to regulate the stretch in all the parts of thefabric, each reel is provided with a coupling, comprising coupling rings26, 27, a lever 28 and a bracket 29. The whole frame of the machine isstrengthcned by traverses 30.

There are tubes 31 provided on each side of the tub l, relied togetherby liquid delivery tubes 32 which serve to sprinkle the fabrie withwashing liquid during its passage in the direction of the arrow. Therebythe te sprinkling medium can be taken from the tub 1 either by means ofthe tubes or the the fabric an overflow 9" is provided, by 65 0U turningof which, as indicated by the arrow, the depth of the liquid can beregulated.

Fig. 3 shows schematically the introduction of the fabric into themachine by means of a feeding-device E.

Fig. e shows schematically the treatment of the fabric in three steps.

The working of the apparatus is as follows: f

The textile goods are placed at least once upon the band in a widelyspread form by the reels, the band then, due to its low speed takes thefabric along steadily and in a plaited form, the fabric, during themotion being thoroughly soaked with washing liquid. rJhereby the levelof the liquid, regulated by means of the overflow is higher than theband. The fabric thus dips into a washing liquid adjustable in heightand is springled at the same time with the same liquid from above. Thefabric being sustained in the fluid can not be compressed by thepressure of the fluid issuing the jets as the water in the tank whoselevel is regulated according to the width of the pleats receives theimpact of the water from the jets, whereas those portions of the pleatsabove the level of the water in the tank are sustained or partiallysupported by the fluid in the tank.

By this way l have the advantage of a thorough soaking of the textilegoods with washing liquid whereby the fabric being moved slowly in aplaited form can stretch and shrink in any direction.

In order that the textile goods may not ner that the upper portions ofthe plaits project above the bath whereby the fabric is substantiallysupported by the flotative effeet of the bath, moving the fabric initsplaited condition through the bath without producing pressure on ortension in the fabric, and snnultaneously with said movement sprinklingthe portions of the plaits projecting above the bath.
